REVERSIBLE WINDOW-SASH- Specification of Letters Patent.

Patented Dec. 27, 1910.

Application filed March 15, 1910. Serial No. 549,505.

To all whom it may concern:

Be it known that I, ERNEST L. REGUIN, citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Reversible l/Vindow-Sash, of which the following is a specification.

This invention relates to a reversible window sash, and particularly to that class of window sash which is slidable as well as reversible.

The primary object of this invention is to provide a window sash which is adapted to be reversed in order to permit of the outside of the glass being conveniently reached for cleaning or other purposes.

Another object is to provide a simple and practical reversible sash which is easily operated, and in which means are provided for automatically locking the sash in its closed position so as to hold the sash secure in the slide bars and prevent warping.

The invention consists of the parts and the construction and combinations of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is an elevational view of the inside of a sash as mounted in accordance with my invention. Fig. 2 is a vertical section of a portion of the sash showing the pivotal mounting and the locking device with the sash in a closed position. Fig. 3 is a similar view partly in elevation showing the sash in an open position. Fig. 4 is a cross section on the line X, X, Fig. 2. Fig. 5 is a cross section 011 the line Y, Y, Fig. 3.

In the drawings, A represents the casing or pulley stile of an ordinary double hung window, which is fitted with a parting strip and stop beads in the usual manner.

B is the window sash which is pivotally mounted, as later described, at the center of gravity of the sides, on slide-bars 2, which are adapted to slide up and down in the frame A in precisely the same way as an ordinary window; sash chains or cords 3 carrying counter-weights 4 being attached to the slide-bars 2, as shown in Flg. l. The ends or stiles a of the sash B are provided with tongues 5, and the adjacent faces of 1, the slide-bars 2 have corresponding grooves 6 so that the sash and slide-bars may fit together with a tongue-and-groove joint.

The sash B is mounted on the slide-bars 2 in the following manner: The bars 2 are each slotted transversely at 7, Figs. 2 and 3, and a plate 8 having studs or pins 9, 9 formed on the ends thereof is loosely inserted in each slot 7, the pivot-pins 9 on the plates 8 extending into socket-plates 10 mounted in the tongues 5 of the sash B, thus supporting the latter on the slide-bars 2. The pins 9 on the plates 8 extend into bearing-bars or shoes 11, which constantly bear against the pulley stiles A, the ends of the plates 8 contacting with the shoes 11 and the sash B in such manner as to prevent any side movement of the latter between the stiles A. The slide-bars 2 are narrower than the width of the space between the frame A -manner that a pin 1 1 eccentrically disposed on the inner end of the hub 13 engages a socket in the plate 8. The outer end of the hub 13 projects through a face plate on the bar 2 and is kerfed to receive a screw driver or like instrument by means of which the hub may be revolved on the pin 14. This pin 14 being eccentric and the plate 8 stationary, the hub 13 acts as a cam-lever and on being turned in the direction of the arrow, Fig. 2, will cause the bar 2 to move downward and backward away from the sash B into the position shown in Fig. 3, a recess 12 in the bars 2 permitting the latter to telescope the bearing bars 11.

As a means of locking the sash B to the slide-bars 2 when in the closed position, Figs. 1 and 2, and rigidly securing the sash at the top and bottom thereto, the following device is employed: A plate 15 is mounted in the groove 6 near each end of the bars 2 and has a tang 16 formed thereon which is adapted to enter a slot 17 in a plate 18, correspondingly mounted on the s eh B, and engage with the upper edge of t e slot, as shown in Fig. 2. When the hub 13 is turned to move the bars 2 downward and outward, the tangs 16 move therewith and are thus withdrawn from the plates 18.

In operation, the sash B and slide-bars 2 being mounted in the frame A as before de-' scribed, and shown in Fig. 1 of the drawings, the sash B, together with thebars 2, may be raised or lowered in the pulley stiles to any desired position in the usual manner, the counter-weights 4c maintaining the sash and bars in the required position.

When it is desired to reverse the sash B, the operator turns the hubs 13, as before described, so as to withdraw the tangs 16 from the plates 18 and the grooves 6 from the tongues 5, and thus separates the sash from the slide-bars 2, as shown in Fig. 3. In this posit-ion the sash B is free to be rotated on the pivot pins 9, thus admitting of its being reversed. To relock the sash B, it is returned to a position in line with the bars 2, and the latter brought back into contact with the sash by means of the hubs 13, the tongues 5 of the sash engaging the grooves 6 of the bars 2 to form a tight joint and the tangs 16 engaging the plates 18 to act against any tendency of the sash or bars to warp or pull apart at this point.

Having thus described my invention, what I claim and desire to secure by Letters-Patent, is:

1. In a reversible window sash engageable with slide-bars slidable in the usual sash grooves, plates fixed to the sash and on which the sash is pivotally mounted, said plates extending through slotted openings in the slide-bars, and said openings being wider than the width of the bars, bearing-bars mounted on opposite ends of said plates, means carried by the slide bars and operating in conjunction with said plates for moving the slide-bars in and out of engagement with the sash, and means for automatically locking said bars to said sash, substantially as described.

2. In a reversible window sash engageable with slide-bars slidable in the usual sash grooves, plates fixed to the sash and on which the sash is pivotally mounted, said plates extending loosely through slotted openings in the slide-bars, and said openings being wider than the width of the bars, bearing bars mounted on said plates, hubs fixed in the slide bars and having a part. engaged eocentrically with said plates, said hubs having means by which they may be rotated to move the slide-bars, and means for automatically locking said bars to said sash, substantially as described.

3. In a reversible window sash engageable with slide-bars slidable in the usual sash grooves, plates fixed to the sash and on which the sash is pivotally mounted, said plates extending loosely through slotted openings in the slide-bars, and said openings being wider than the width of the bars, bearingbars mounted on said plates, hubs engaged eccentrically with said plates, said hubs being mounted in the slide-bars, and

having means by which said hubs may be rotated so as to move said slide-bars in and out of engagement with the sash, and means for automatically locking said bars to said sash, substantially as described.

5. In combination with the pulley stiles of a window frame, slide bars slidable on said stiles, pivot carrying plates mounted loosely in said slide bars, a window sash pivotally connected to said slide-bars on said pivot plates, said plates being fixed to the sash, hubs mounted in said slide-bars, at right angles to said plates, eccentric connections between the inner ends of said hubs and said pivot plates, and means by which said hubs may be rotated so as to move said slide-bars in and out of engagement with the sash.

I

In combination with the pulley stiles of a window frame, slide bars slidable on said stiles, pivot carrying plates mounted loosely in said slide bars, a window sash pivotally connected to said slide-bars on said pivot plates, said pivot-carrying plates being fixed to the sash, hubs mounted in said slidebars at right angles to said plates, eccentric connections between said hubs and said pivot plates, means by which said hubs may be rotated so as to move said s1ide-bars in and out of engagement with the sash, tangs on said s1ide-bars, and slotted plates on said sash adapted to be engaged by said tangs so as to lock the bars to the sash.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
